HENRY J. MARTIN, OF CHICAGO, ILLINOIS ASSIGNOR TO THE WHITMAN dz BARNESMANUFACTURING COMPANY, OF AKRON, OHIO.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 544,738, dated August20, 1895.

Application filed May 7,1895. Serial No. 548,417. (No modal.)

To all whom it may concern.-

Be it known that I, HENRY J. MARTIN, a citizen of the United States,residing in the city of Chicago, county of Cook, and State of Illinois,have invented a certain new and useful Improvement in Wrenches, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings.

My invention has for its object the providing a wrench which, whilebeing capable of taking nuts or bolts of a number of different sizes infixed jaws, shall be compact and neat. It also contemplates thecombination in the same instrument of both a wrench .of my improveddesign and a screwdriver or other useful tool.

The invention consists ofa handle to which is pivoted, intermediate oftheir ends, one or more revoluble bars, which have formed on them, onopposite sides of the pivot, two pairs of wrench-jaws adapted to takedifferen t-sized nuts, or one pair of jaws and a screwdriver or othersuitable tool, there being means pro- Vided for holding the revolublebars" in the desired position.

The drawings illustrate three embodiments of my invention.

Figure l is a plan of one form considering the wrench as lying on itsflat side; Fig. 2, a side elevation of the same; and Fig. 3, a sectionalplan with the top plate removed. Figs. 4 and 5 are each plans of otherforms of my improved wrench. r

a and b are two plates which form the handle of the wrench. Pivoted tothese plates near one end thereof, by means of the bolt 0, is arevoluble bar d. This bar has each of its ends formed into a pair ofwrench-jaws of different capacity. A blockt is provided between theplates a and b for the purpose of locking either end of this bar to thehandle, so that the other end may be used as a wrench. This block isformed as shown, having a portion f of the proper width to fit betweenthe pair of jaws which are nearer together, and a portion g, which isadapted to occupy the space between the pair of greater capacity. Thisblock has also a top lug e, which pro jects through an elongated hole hin the top plate a. The block is slidable longitudinally of the plates,being guided by the sides of the hole It and the lug 'e, which latterclosely fits the width of the hole. A spring t' (shown in dotted lines)is carried in a depression on the under side of the block, and bearingagainst the plate I) forces the block against the plate a and holdsit inwhatever position it is placed. In the form shown in Figs 1, 2, and 3there is a similar revoluble bar pivoted near the other end of theplates. One end of this bar has wrench-jaws, but the other is made intoa screwdriver, as shown. The sliding blockj is, therefore,correspondingly changed, it being made of the proper width to slidebetween the jaws on the bar, and also having a notch la in it of a sizeto fit eachside of the screwdriver end 1 of the bar, and thereby lockthe same in place. In the form shown in Fig. 4 a stationary plate fillsthe space between the plates a and b at this end of the handle, andnotches m, n, and 0, to receive different-sized nuts or bolts, arecutinto the plates. In Fig. 5 a similar plate is placed between theplates at and b, but its end extends out and is formed into ascrewdriver p. Wrench-jaws are also formed in this end by means of thenotches 'r and 3 cut into the plates.

. In operation, when it is desired to use the locked end of the bar, theblock is simply slid away from the bar by means of a pressure of thethumb upon the projecting lug e, the bar reversed, and the block slidback to grasp the other end of the bar.

The arrangement of the notches in the handle and of the revoluble barsand the tools formedon them will be varied to suit the requirements ofthe art in which'the wrench is intended to be used.' In place of ascrewdriver any other suitable tool capable of being held by the slidingblock may be used.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a wrench, in combinati0n,'a handle, a bar pivoted intermediate ofits ends to the same, a pair of wrench jaws formed on this bar on oneside of the pivot, a suitable tool formed on the bar on the other sideof the pivot, and ablock connected with the handle and adapted tooccupythe space between the wrench jaws and also adapted to hold thetool,

ICO

. to occupy the space between the other pair of said jaws, and meanswhereby said block may be slid into the space between the pair of jawspresented to it, substantially as described.

3. In a wrench, in combination, the plates a and b, the revoluble bar atpivoted between them, said bar having each of its ends formed into' apair of wrench jaws, the block t slidable between said plates and havinga portion f adapted to fit between one pair of said jaws and a portion gadapted to fit between the other pair, said block having a lugprojecting through a hole in the plate a, and the spring t forcing theblock against one of the plates, substantially as described.

HENRY J. MARTIN.
